How to Run for Office in South Dakota
Getting on the Ballot
South Dakota runs on nominating petitions: legislative, statewide, and federal candidates circulate party petitions and file them with the Secretary of State, with signature counts pegged to a percentage of the party's last gubernatorial vote; county candidates do the same with the county auditor. Circulation opens in early January and petitions are due in late March before the June primary.
The petition format rules are the trap: each sheet must be fully self-contained - heading, signer instructions, signature lines, and circulator's verification all pre-printed - and printed front-and-back on a single sheet; taped, stapled, or glued sheets and signature-lines-only pages are rejected outright. The SOS publishes office-specific petition forms and a validation chart; use them exactly.
One structural oddity: while governor and most offices are nominated at the primary, several down-ballot statewide offices are nominated at party conventions rather than by primary voters - so the path for those offices runs through party delegates, not a primary campaign. Confirm the current convention-office list with the Secretary of State for your cycle.
Where Local Candidates File
The county auditor is the filing office for county candidates (and the seller of the official voter registration list, which state rules require them to charge for); school and municipal candidates file with their district's business manager or municipal finance officer on the consolidated local calendars. A county commissioner candidate also files a Statement of Financial Interest with the auditor within 15 days of filing petitions - statewide and legislative candidates file the same with the Secretary of State.
Campaign finance runs through the Secretary of State's online filing system: a Statement of Organization is due within 15 days of becoming a candidate (crossing $500 in activity is the trigger), and - per a 2025 law change - legislative and county partisan candidates now file a pre-primary report as well.
Worth Knowing
- Sheet format is destiny: self-contained, front-and-back, no assembly - the SOS's downloadable petition forms exist so you don't improvise.
- Some statewide offices are convention-nominated, not primary-nominated - a genuinely different campaign (delegates, not voters).
- The 15-day Statement of Financial Interest after filing petitions is the follow-up filing candidates forget.
- The 2025 pre-primary report requirement is new - older guides won't mention it.
